One of the largest Biogas Plants in Switzerland goes for PVC-U Systems

Recycling biogenic waste for energy is a highly promising and sustainable concept for energy production and at the same time has a positive impact on the environment. One of the largest and most modern biogas plant in Switzerland produces 1.9 million m3 of biogas annually.

SwissFarmerPower Inwil (SFPI) near Lucerne utilizes highly integrated
and innovative process technology in order to convert 61,000 tons of
biomass into biogas every year. Liquid manure, garden waste and
biowaste from agriculture and the food industry are processed, treated
and the resulting biogas is fed into the regional natural gas network.
PVC-U system solutions from GF Piping Systems make sure that treatment
processes within the plant, for example ultrafiltration and reverse
osmosis, are efficient and reliable.

Fermentation residue processing with diaphragm valves

Before conducting the liquid phase into the sewage system, the
fermentation residue must be processed as the excess water from
fermentation contains high amounts of solids, ammonium nitrogen, other
nutrients and salts. This task is handled in a total fermentation
residue processing system with the treatment steps: solids/liquids
separation and diaphragm filtration. At the center of customer
requirements are an economic pricing strategy in the sense of
cost-conscious energy production, high material resistance and a long
product service life. The components used, i.e. diaphragm valves, ball
valves, pressure reducing valves as well as PVC-U pipes and fittings,
are specifically adapted to the media, temperatures and pressures in a
biogas plant.

Maximum quality standard

Only products made of high-quality materials are used in the biogas
plant in Inwil. High availability of spare parts is guaranteed.
Additionally, the engineers and users have access to comprehensive and
high-quality documentation. Besides price lists, product documentation
and other downloadable information, the extensive CAD library
contributed to the success of this project. The customer also
particularly appreciates the personal contact to sales reps and the
on-site support.
